A fluid battery that can take any shape. (liu.se)

Using electrodes in a fluid form, researchers at Linköping University have developed a battery that can take any shape. This soft and conformable battery can be integrated into future technology in a completely new way. Their study has been published in the journal Science Advances.

Actual new battery tech? I didn't see the capacity listed/compared to a normal lith-ion of the same volume but it does say they have some issues with voltage. I'm not sure how annoying that actually is (not super good with electricity) but this looks rather promising. Might see smart watches and similar devices without any flat hard surfaces using these combined with flexable screen tech. Course like always this stuff is extremely reliant on the capacity being workable, if it's too much less than the equivalent in lith-ion it's just not going to get used.

An inconsistent voltage is a bit of a deal breaker if it's a significant swing. For example, AA batteries are supposed to be 1.5v. Typically you can measure them at 1.7v when they're brand new, and that's fine. The voltage will drop as it's used and devices tend to stop functioning when the battery reaches about 1.3v.

That's a fairly narrow range of voltage required to keep the device working correctly.
